Abstract: Un procédé et un dispositif pour détecter la séquence d'apprentissage d'un égaliseur autoadaptatif appartenant à la partie réception d'un système de transmission synchrone de données. Cette séquence d'apprentissage est précédée par l'émission de données transformées au codage en une suite de symboles multivalents ayant un spectre de fréquence se réduisant pratiquement à une raie de grande amplitude et commençant par l'émission de données transformées au codage en au moins un symbole nul. Le procédé consiste à détecter la présence de la raie de grande amplitude dans le signal formé des symboles reçus mais non égalisés grâce à un filtre numérique et à détecter la première chute importante de l'amplitude absolue de ce signal succédant à la détection de la raie et se maintenant au moins pendant la durée d'un symbole grâce au détecteur de bas niveau d'amplitude. Le procédé s'applique à la détection de la séquence d'apprentissage d'égaliseur recommandée dans l'avis V 37 du CCITT.

Abstract: INVENTION:  Automobile Washing Apparatus INVENTOR:   Ronald McIntyre and Ivan J. Barber ABSTRACT OF THE DISCLOSURE     A washer arm assembly for use in washing a vehicle moving relative to the washer arm assembly is described.  The assembly includes a support frame, and a pivoting arm assembly including a primary arm pivotally connected to the frame and a secondary arm pivotally connected to the primary arm.  A wash brush is rotatable mounted to the secondary arm for rotation about a vertical axis.  Motion of the arm assembly is guided by a telescoping control rod pivotally connected to each of the secondary arm and the frame, a pneumatic cylinder which urges pivotal movement of the arm assembly in a predetermined angular direction, and a stop which limits the pivoting movement whereby the arm assembly locates in a rest position in which the brush is positioned in the path of the vehicle.  The direction of rotation or the brush and the relative location of the pivotal axes of the various members are so selected that in use the brush is constrained to travel across the front of the vehicle, along one side, and then across the back of the vehicle while returning to the rest position.  No position sensing switches or hydraulic controls are required to guide the arm assembly.

Abstract: BALL VALVE AND SEAT ASSEMBLY                     Abstract of the Disclosure A ball valve having an improved relationship between the ball and associated seat rings and an improved seat ring design.  The ball is mounted for selective rotation and limited axial movement in a valve body passageway.  Seat rings disposed on diametrically opposite sides of the ball about valve inlet and outlet openings each include a ball engaging surface having an arcuate contour.  At a relaxed preassembly reference position, the radius of curvature of the ball engaging surface is greater than the radius of curvature of the ball.          Frusto-conical disc springs interposed between each seat ring and an associated valve body shoulder additionally urge the seat rings into engagement with the ball.  A reinforcing ring disposed at the forward end of each seat ring acts as a rigid bearing surface.  Component sizing is such that in the assembled valve, the seat rings are slightly rotatably flexed in response to the engaging surfaces thereof engaging the ball such that the surfaces are distorted to have a mating relationship with the ball.  At the same time, the disc springs are compressed while continuously urging the seat ring ball engaging surfaces into ball engagement.

Abstract: EXTENSIBLE MULTI-PLY TISSUE PAPER PRODUCT               Paul D. Trokhan ABSTRACT An extensible multi-ply tissue paper product having high tensile energy absorption (TEA); high liquid absorbency; and, preferably, high tensile strength efficiency.  The product comprises plies which are preferably embossed and discontinuously adhered together.  The product has high tensile energy ab-sorption by virtue of having substantial extensibility in the machine direction which, preferably, results from its constituent plies having substantial MD ex-tensibility induced by having undergone wet and/or dry foreshortening during their manufacture.  The product has synergistically high liquid absorbency by virtue of at least two plies of the product having sufficiently different stress/strain properties that one ply will sufficiently constrain unadhered portions of the other ply from being elongated in the plane of the paper when wetted that such unadhered portions of the constrained ply will pucker in the Z-direction as its foreshorten-ing-induced internal stresses are relieved.  Prefer-ably, the constraining ply is high bulk, wet-micro-contracted tissue paper, and the other ply is dry-foreshortened tissue paper,  e.g., dry-creped tissue paper.  Also, the plies of preferred embodiments preferably have nominally equal MD extensibilities at rupture.  Such preferred products have high tensile strength efficiency which is manifested by their having monomodal stress/strain characters.  Embodiments of the invention such as two and three ply paper towels are especially useful for spill wipe-up applications.

Abstract: ABSTRACT OF THE DISCLOSURE            A burner nozzle assembly is disclosed for atomizing liquid fuel at lower emission velocities, and comprises an axially extended nozzle body and a nozzle cap mounted forwardly thereon, the nozzle cap and nozzle body cooperating to define a flow reversing fluid path for the liquid fuel, to cause the fuel to move essentially countercurrent to its initial direc-tion of flow, and to the flow of an auxiliary fluid disposed in an outer coaxial conduit.  The reversal of flow of the liquid fuel, promotes a collision between it and the auxiliary fluid, to facilitate thorough atomization, without the need for in-crease in emission velocities, that results in higher fuel consumption and reduced per capita fuel utilization and heat radiation.  The nozzle is adapted to operate in a variety of burner assemblies, including conventional burner guns, and is of simple construction.
